Choosing The Right Metal Finishing For Your Product

If you own or manage a production facility that creates metal products, you will need to invest in a metal finishing machine of some sort. There are many different ways of finishing a metal product so that it's ready for a consumer, or so that it can be used in other production facilities, and understanding details of these methods can help you determine the best choice for your process. Consider the following.

1. Metal plating

This method involves a bath that coats a product with metal, and an electrical current permanently applies the metal to the substrate. This process is very durable and creates a long-lasting finish, and can be used to apply just about any type of metal to a variety of materials--hard chrome plating is just one example. It is so durable and creates such a thick finish that plating is even used for jewelry. It offers corrosion resistance, flame resistance, and a smooth finish for a product. It is also a good option for coating other metals.

2. Brushed metal

This process uses a wire or metal brush that is run over the surface of metal to smooth out imperfections and create a more attractive finish. In some brushed metal applications the brushstrokes are purposely visible. You may notice these in locks and other small metal items; the brushstrokes actually provide for better grip than a completely smooth surface.

3. Buff polishing

A buff polisher is used to create the smoothest finish for metal and to create a more attractive finish. For products that are sold to a consumer and to smooth out solid metal products, buff polishing is typically the process used.

A buff polishing machine can even be used to round out edges of a metal product, but is not meant for exact processes. It also may not be the best for fragile items because of how it applies pressure in the buffing process.

4. Powder coating

This type of finish produces a result that resembles paint but which is much more durable and long-lasting on metal. A powder of any color and texture is applied to a metal product and then melted so it adheres permanently to the metal's surface. Powder coating does not chip or rust and can last for years, even in poor weather conditions. It's often used for metal fences and other metal products that are used outdoors.

Consider these processes for finishing your metal product so you know to invest in the right machinery and equipment for your production facility.
